You and Luis were friends. Not the best, you weren't that close, but that didn't stop you from falling head over heels in love with him. Although anyone would have loved his charming charisma.
Everyone seemed to notice your amorous glances and casual touches, except Luis. Even your friends made fun of you for your affection for him, so much so that they decided to give you an awesome birthday present. A full-size cardboard version of Luis.
You laughed about it and on New Year's Eve you dressed up "your" Serra in tinsel and a Santa Claus hat. But who knew that one day, by chance, Luis would find himself in your flat with a cardboard cutout of himself.
"Wow, that's my brother!" He says as he walks up to the cardboard self and puts his arm round his shoulder just to avoid embarrassing you as he quickly realises the situation. "Do we look alike?"
